OVERHEAD CAR 0R LIKE RECEPTAC'L'E.

SPECIFICATION forming part of Letters Patent 1Y0. 605,620, dated June 14, 1898.

Application filed-Tannery 15,1297. BeXlElNO- 619,326. on. model.)

To ,allwlwrn it may concern.-

Be it known that I, ALFRED M. AckLIN, a resident of Pittsburg, in the county of Allegheny and State'of Pennsylvania, have invented a new and useful Improvement in Overhead Cars or Like Receptacles; and I do hereby declare the. following to be a full, clear, and exact description thereof.

My inventionrelate's to door-operating dovlces suchas may be applied to receptacles for carrying'sand, coal, or other materials, its object being to provide a simple form of apparatus whereby the doors in the bottom of suchreceptacles may be quickly opened and closed, and automatically, if desired.

My invention comprises, generally stated, a suitable receptacle having doors hinged at the bottom thereof closing said receptacle [and adapted toswing down therefrom to discharge the contents of said receptacle, a rocking shaft journaled within said receptacle,

. connections. between said rocking shaft and a toggleg'oint connected to said doors, mechanism for turningsaid' shaft whereby the doors will drop down of their own accord to discharge the contents of the receptacle.

To enable others skilled in the art to make and use my invention, I will describe the same more fully,- referringto the accompanying drawings, in which- Figure 1 is a vertical sectional view of a receptacle with my invention applied thereto. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is an enlarged detail sectional view of the lower part of the receptacle, showing the manner in which the doors arehinged thereto more clearly. Fig. 4 is a view of the receptacle from the opposite side to that shown in Fig. 1, partly broken away and showing the doors open. Fig. 5 shows a modified form of my invention.

"ceptaclo illustrated or the manner in which said receptacle is transferred from one place to another. The invention applies as well ing riveted together in such a manner as to form a strong and rigid receptacle for the reception of sand, coal, ashes, or other materials. This receptacle 8 has the inclined sides 6 and is closed at the bottom by the doors f f, said doors. being hinged in any suitable manner, so that when released they willswing down to the position shown in Fig. 4. One of the doors f has the strip f" on its outer end, which is adapted to overlapthe door f and so form a tight joint to prevent the es- 7o cape of any of the contents of the receptacle e.

J ourn aled within suitable bearings h in the sides of the receptacle 6 is the rocking shaft 1', one end of said rocking shaft having thetrip-lever It secured thereto. The lever k has the weightl secured thereto, said weight being preferably made adjustable by means of the set-screw Z. I

Within the receptacle e and secured to the a.

rocking shaft 1' is the arm m, the lower end of said arm having the collar m formed thereon surrounding said shaft. Pivoted to the outer end of the arm m is the bent lever '11, the lower end of said bent lever n'being pivoted to the toggle o, the arms 0 of said toggle being connected to the eyebolts pen the doors ff.

Secured to the beam win the arm r, with the depending arm r secured thereto, said depending arm'r' being in the path of the trip-lever It as the trolley 0 moves along the overhead rail.

The operation of my invention when in the form described is as follows: The receptacle c, with thedoors closed and the parts in the position sbewn in Fig. 1, is filled with sand or other material and is conveyed along to the -'dumpingplace bymeans of the trolley c. The

arm m, when in the position shown in Fig. 1, I00

A trolley c has the trolley-wheels 55 will act to hold the doors in their closed position. This is due to the fact that the arm m is beyond the center of the shaft 2'. The bent lever n, resting at or about its mid-point against the collar on of the arm m, prevents said arm from being drawnbeyond a certain fixed point, which is just. beyond the center of the shaft 1'. When the receptacle arrives at the dumping-point, the upper end of the trip-lever kwill come in contact with the depending arm r, whereupon the rocking shaft 'Lwill be turned, throwing the arm m on the opposite side of the center of the shaft 1', so that the weight of thecontents of the receptacle will be permitted to act on the doors ff and cause them to swing down. When the doors have opened to their full extent, the parts will be in the position shown in Fig. 4. When the contents of the receptacle have been discharged, the lever k,-throngh-the cooperation of the stop 1- will be carried back to its normal position, and by the same movement the doors will be raised and the parts brought back to the position shown in Fig. 1, witlnthe arm m beyond the center of the shaft t'. The recepmale is then ready to be conveyed back to the point whereit is refilled, when it is again conveyed .to the dumping-point and the parts are again operatcd'in the manner described. If it is not desired to operate the doors automaticallyythe trip-lever k may be dispensed with and a hand-wheel may be mounted on ,the shaft 2', such as shown in dotted lines, Fig. 4, whereby said shaft'may be turned to open and close the doors.

In 'caseswhere it might be inconvenient to have anyof the operating mechanism containe'dwithin the receptacle, as shown in Fi'g. 1, or where the material to be conveyed is of such character as to create severe wear upon the parts contained within the receptacle, all the operatingparts, except the rocking shaft, may be on the exterior of the receptacle, as shown in Fig. 5. In that case the receptacle 8 has the shaft 3 journaled therein, said shaft having the trip-lever z, secured thereto, car- Tying the weight t. The shaft 5 has also the armsu at each end thereof, said arms having the bent leversv pivoted thereto and the lower'ends of said levers'v attached to the toggles w. The doors a: are hinged in the same mannerasbeforc. The operation of this form of my invention is the same as that hereinbefore described, and a fuller description of the same 1s not deemed necessary.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. In overhead cars and like receptacles, l

the combination with a suitable receptacle, of a downwardly-opening door,a rocking shaft 'mounted on said rece tacle, a toggle connected to said door, an connections between said shaft and said toggle, substantially as set forth. r

2. In overhead cars and like receptacles, the combination with a suitable receptacle, of a downwardly-swinging door, a rocking shaft mounted on said receptacle, a trip-lever mounted on said shaft, aweight on the lower end of said trip-lever, a toggle-j oint connected to said door, andconnections between said shaft and said toggle-joint, substantially as set forth.

3. In overhead cars and like receptacles, the combination with a suitable receptacle, of adownwardlysopeningdoor,a rocking shaft mounted on said receptacle, an arm on said shaft, and connections between said arm and said door, the upper end of said armbeing normally beyond the center of said shaft, substantially as set forth.

4. In overhead cars and like receptacles, the combination with a suit-able receptacle, of a downwardly-opening door, a rocking shaft 'mgunted on said receptac1e,'a trip-lever mounted on said shaft, an arm on said shaft,

a toggle'connccted to said door, connections between said arm and said toggle, the upper end of said arm being normally beyond the center of said shaft, substantially as set forth. 5. In overhead cars and like receptacles,

' the combination with a suitable-receptacle, of

a downwardly-swinging door, a rocking shaft mounted on said receptacle, a trip-lever moon on said shaft-,an arm on saidshaft, a bent lever pivoted tothe upper end of said arm, a toggle connected to the lower end of said bent lever and to said door,- the upper end of said arm being normally beyond the centerof said shaft, substantially as set forth.

6. In overhead cars and like receptacles, I

the combination with 'an overhead beam, of a trolley moving thereon, a receptacle suspended from said trolley, a downwardlyswinging door, a rocking shaft mounted on said receptacle, a trip-lever on said shaft, connections between said shaft and said door and atrip on said overhead beam in the path of said trip-lever, substantially as set forth.

In testimony whereof I, the said ALFRED M. ACKLIN, have hereunto set my land.
